You've tried to sell us on that before, with few takers. This proposed
use-case impresses me even less than the previous ones, because callers
of xslt_process seem quite likely to need to work with non-constant
parameter names.

In any case, given what we have at the moment for function overload
resolution rules, I think it's a fundamentally bad idea to introduce
a "wild card" function type that would necessarily conflict with
practically every other possible function declaration. So regardless
of what use-cases you propose, I'm going to vote against that.
